+class ConsistencyLevel:
+ """
+ The ConsistencyLevel is an enum that controls both read and write
+ behavior based on the ReplicationFactor of the keyspace. The
+ different consistency levels have different meanings, depending on
+ if you're doing a write or read operation.
+
+ If W + R > ReplicationFactor, where W is the number of nodes to
+ block for on write, and R the number to block for on reads, you
+ will have strongly consistent behavior; that is, readers will
+ always see the most recent write. Of these, the most interesting is
+ to do QUORUM reads and writes, which gives you consistency while
+ still allowing availability in the face of node failures up to half
+ of <ReplicationFactor>. Of course if latency is more important than
+ consistency then you can use lower values for either or both.
+
+ Some ConsistencyLevels (ONE, TWO, THREE) refer to a specific number
+ of replicas rather than a logical concept that adjusts
+ automatically with the replication factor. Of these, only ONE is
+ commonly used; TWO and (even more rarely) THREE are only useful
+ when you care more about guaranteeing a certain level of
+ durability, than consistency.
+
+ Write consistency levels make the following guarantees before reporting success to the client:
+ ANY Ensure that the write has been written once somewhere, including possibly being hinted in a non-target node.
+ ONE Ensure that the write has been written to at least 1 node's commit log and memory table
+ TWO Ensure that the write has been written to at least 2 node's commit log and memory table
+ THREE Ensure that the write has been written to at least 3 node's commit log and memory table
+ QUORUM Ensure that the write has been written to <ReplicationFactor> / 2 + 1 nodes
+ LOCAL_QUORUM Ensure that the write has been written to <ReplicationFactor> / 2 + 1 nodes, within the local datacenter (requires NetworkTopologyStrategy)
+ EACH_QUORUM Ensure that the write has been written to <ReplicationFactor> / 2 + 1 nodes in each datacenter (requires NetworkTopologyStrategy)
+ ALL Ensure that the write is written to <code><ReplicationFactor></code> nodes before responding to the client.
+
+ Read consistency levels make the following guarantees before returning successful results to the client:
+ ANY Not supported. You probably want ONE instead.
+ ONE Returns the record obtained from a single replica.
+ TWO Returns the record with the most recent timestamp once two replicas have replied.
+ THREE Returns the record with the most recent timestamp once three replicas have replied.
+ QUORUM Returns the record with the most recent timestamp once a majority of replicas have replied.
+ LOCAL_QUORUM Returns the record with the most recent timestamp once a majority of replicas within the local datacenter have replied.
+ EACH_QUORUM Returns the record with the most recent timestamp once a majority of replicas within each datacenter have replied.
+ ALL Returns the record with the most recent timestamp once all replicas have replied (implies no replica may be down)..
